Specification of Letters Patent.

Patented Oct. 31, 1905.

Original application filed March 27, 1903, Serial No. 149,874. Divided and this application filed September 24,1903. Serial No. 174,466-

To all whom it may concern:

Be it known that I, THOMAS Oox, a citizen of the United States, residing at Portland, in the county of Multnomah and State of Oregon, have invented certain new and useful Improvements in Oonveyers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to improvements in conveyers, and particularly such as are adapted for handling ore and minerals or other heavy substances.

The invention comprises certain novel constructions, combinations, and arrangements of parts,as will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 represents a view in side elevation of a conveyer embodying the features of the present invention. Fig. 2 represents a top plan view of the same. Fig. 3 represents a transverse vertical section, taken generally on the plane of line 3 3 of Fig. 1.

Referring to the drawings by numerals, 1 indicates a rear truck and 2 a front truck supporting a platform, as 3. The platform 3 is mounted upon a block 4, at its rear end journaled on the truck 1 on the shaft 1 for permitting pivotal movement of the said end of the platform, and the forward end of the said platform is supported by a jack-screw 5 or a plurality of such screws carried by the truck 2 and adapted to be threaded up and down for raising and lowering the forward end of the platform 3. Spaced apart and rising from the platform 3 are suitable standards 6 6, carrying a conveyer-framework 7. The framework 7 extends for a portion of its length in an inclined plane slanting toward the front of the platform 3 and extending beyond and below the same, the forward end of said framework resting directly upon and being supported by the said forward end of the platform. The rear upper end of the inclined portion of the platform 7 is supported by the rearmost standards 6. The framework 7 extends rearwardly from the rearmost standards 6 in a horizontal plane. The horizontal portion of the framework 7 is of sufficient length for overhanging a suitable car or other receptacle 8 for discharging the material conveyed into the same. The'framework 7 is made up, preferably, of side pieces 9 9, secured together and braced by cross-rods 10, the upper inner surface of said side pieces being provided with wearing-plates 12 and 13, the plates 13 being preferably disposed at an incline relative to the vertical plane of the respective side pieces. Journaled in the lower end of the framework 7 is a drum 14, and extending through slots in the framework are the journals of said drum, which are carried by boxes 15, which are slidably mounted and movable longitudinally of the frame 7 and engagedby threaded shafts or bolts 16 for moving such boxes and locking the same in given positions, thus facilitating the adjustment of the drum 14 longitudinally of the framework for belt-tightening purposes. The rear upper end of the framework 7 carries a drum 17, similar to drum 14 and similarly mounted, with its journal projecting through longitudinally-disposed slots in the framework 7 and engaging longitudinallymovable bearing-boxes 18, designed to be adjusted and retained in various adjusted positions by engaging bolts 19. Passed about the drums 14 and 17 is an endless conveyerbelt 18, having its carrying portion supported by a series of rolls 19, journaled in the framework 7 in position for contacting with the under surface of said carrying portion of the belt. The return portion of the belt is supported by rolls 20, journaled in the framework 7,0f peculiar construction hereinafter fully set forth.

The belt 18, as best seen in Figs. 2 and 3, is made up of a web of canvas, rubber, or other suitable material 21, carrying a series of metal wearing-slats 22, spaced a comparatively short distance apart and fixed to the belt transversely of the same. At intervals in the length of the belt are positioned laterally-projecting bars or fins 23, each fin being formed from one web of an angle-bar 24, which bar is fixed to the web 21 between two of the slats 22. The webs 23 are of course arranged in the same vertical plane transversely of the belt, but are spaced apart longitudinally with respect to each other and lie in different longitudinal planes of the belt. The fins thus constructed are adapted to carry a maximum load, while at the same time permitting of the use of rolls 20 for supporting the return portion of the belt, said rolls, as seen in Fig. 3, consisting of a shaft 25, carrying end pulleys 26 and an intermediate pulley 27, the end pulleys engaging the edges of the belt outside of the webs 23 and the intermediate pulley engaging the central portion of the belt between such webs.

Journaled in the framework 7 at the juncture between the inclined and the horizontal portion thereof is a drum 28, directly supporting and assisting in the driving of the belt 18, said belt forming its angle over said drum. The shaft of the drum 28 carries a drive-pulley 29, belted to a similar pulley 30, carried by the shaft of the drum 17, whereby power may be conveyed from the shaft of drum 28 to the belt 18 through the drum 17 for driving such belt. The shaft of the drum 28 receives power through a drive Wheel 30, carried thereby and connected with any suitable motor 31, supported and carried by the platform 3 by the belt 31*. I

In operation a load is deposited upon the belt 18 at the lower end of the framework 7, either manually or by any suitable mechanism, and as the belt moves up the incline the load will be conveyed throughout the length of the framework 7 and discharged at the rear end thereof. T he particular form of belt employed not only facilitates the handling of a load of comparatively great weight, but is designed to resist too rapid wear under the grinding and cutting action of ore and rock, while the plates 12 and 13 protect the side pieces of the framework 7 and effectually prevent destruction thereof. In the handling of materials designed to be conveyed by the present improved mechanism it is essential that means be provided for guarding against undue wear, and the arrangement of metallic slats, angle-irons, and wearing-strips is adapted to effectually accomplish this result.

In depositing a load upon the conveyer it is sometimes found desirable to have the lowermost end of the framework 7 in one horizontal plane and at other times have the same in another horizontal plane, the height of such end facilitating the depositing of a load onto the conveyer. I have therefore provided means for facilitating the raising and lowering of such lower end of the framework, which consists simply in the tilting of the platform 3 by the actuation of the jack-screws 5 for moving said platform upon its pivot.

The present application is designed for presenting and claiming the details of my improved conveyor and constitutes a division of my former application for a patent for improvements in automatic excavating and shoveling mechanism, filed March 27, 1903, and designated by Serial No. M9674.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a conveyer, the combination of a conveyer-framework, of a conveyer-belt carried by said framework, fins projecting laterally from said belt in different longitudinal planes thereof, and supporting means arranged beneath said belt and positioned for contacting only with the edges and the intermediate portion of the return lap thereof and permitting the passage therebetween of said fins.

2. In a conveyer, the combination with a framework, of a belt movable longitudinally thereof, wearing-slats fixed to the carryingsurface of said belt, angle-bars secured to the belt at intervals intermediate the length thereof, fins projecting from each of said anglebars, the fins of each angle-bar being spaced apart centrally, and supporting means engaging the edges and center of said belt for supporting the same and permitting passage of said fins.

3. In a conveyer, the combination with a conveyer-framework and belt mounted thereon, fins projecting laterally from said belt in the same transverse plane but in different longitudinal planes of the belt, and supports arranged in different longitudinal planes of the belt, and positioned for contacting with the edges and central portion of the return lap of the belt, and permitting the passage of said fins therebetween.

4. In a conveyer, the combination with a framework and a conveying-belt arranged therein, of fins projecting laterally from said belt and arranged in longitudinal rows spaced apart, and supporting-rollers for the return portion of said belt, each of said rolls com prising a shaft journaled in said framework, and intermediate and side pulleys carried thereby adapted to contact with the belt in different longitudinal planes thereof from those occupied by said rows of fins.

In testimony whereof I hereunto affix my signature in presence of two witnesses.

THOMAS COX.
